We initially +target powerpc-ieee1275, but the code should be extensible to other +platforms. + +Usually these signatures are appended to a file without modifying the +ELF file itself. (This is what the 'sign-file' tool does, for example.) +The verifier loads the signed file from the file system and looks at the +end of the file for the appended signature. However, on powerpc-ieee1275 +platforms, the bootloader is often stored directly in the PReP partition +as raw bytes without a file-system.

signedData messages. Only a single signerInfo is supported, + which is all that the Linux sign-file utility supports creating + out-of-the-box. Only RSA, SHA-256 and SHA-512 are supported. + Any certificate embedded in the PKCS#7 message will be ignored. + + - X.509 certificates: at least enough to verify the signatures on the + PKCS#7 messages. We expect that the certificates embedded in grub will + be leaf certificates, not CA certificates.

It shares lots of logic with shim-lock verifier about what + files need to be verified and what modules are unsafe to have loaded. + + - commands to manage the list of trusted certificates for verification. + +Similar to the PGP verifier, if a certificate is embedded in the core +image, verification will be enforced unless disabled on the the grub +command line or by load_env. + +Thus, as with the PGP verifier, it is not a complete secure-boot solution: +other mechanisms must be used to ensure that a user cannot drop to the +grub shell and disable verification. + +Signed-off-by: Daniel Axtens +--- + grub-core/Makefile.core.def | 12 + + grub-core/commands/appendedsig/appendedsig.c | 644 +++++++++++++++++++++++++++ + include/grub/file.h | 2 + + 3 files changed, 658 insertions(+) + create mode 100644 grub-core/commands/appendedsig/appendedsig.c + +diff --git a/grub-core/Makefile.core.def b/grub-core/Makefile.core.def +index fd1229c6328..1cf6b60f82e 100644 +--- a/grub-core/Makefile.core.def ++++ b/grub-core/Makefile.core.def +@@ -921,6 +921,18 @@ module = { + cppflags = '-I$(srcdir)/lib/posix_wrap'; + }; + ++module = { ++ name = appendedsig; ++ common = commands/appendedsig/appendedsig.c; ++ common = commands/appendedsig/x509.c; ++ common = commands/appendedsig/pkcs7.c; ++ common = commands/appendedsig/asn1util.c; ++ common = commands/appendedsig/gnutls_asn1_tab.c; ++ common = commands/appendedsig/pkix_asn1_tab.c; ++ cflags = '$(CFLAGS_POSIX)'; ++ cppflags = '-I$(srcdir)/lib/posix_wrap'; ++}; ++ + module = { + name = verifiers; + common = commands/verifiers.c; +diff --git a/grub-core/commands/appendedsig/appendedsig.c b/grub-core/commands/appendedsig/appendedsig.c +new file mode 100644 +index 00000000000..5d8897be5c8 +--- /dev/null ++++ b/grub-core/commands/appendedsig/appendedsig.c +@@ -0,0 +1,644 @@ ++/* ++ * GRUB -- GRand Unified Bootloader ++ * Copyright (C) 2020 IBM Corporation. ++ * ++ * GRUB is free software: you can redistribute it and/or modify ++ * it under the terms of the GNU General Public License as published by ++ * the Free Software Foundation, either version 3 of the License, or ++ * (at your option) any later version. ++ * ++ * GRUB is distributed in the hope that it will be useful, ++ * but WITHOUT ANY WARRANTY; without even the implied warranty of ++ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

A file ++with an appended signature ends with the magic string: ++ ++@example ++~Module signature appended~\n ++@end example ++ ++where @code{\n} represents the carriage-return character, @code{0x0a}. ++ ++To enable appended signature verification, load the appendedsig module and an ++x509 certificate for verification. Building the appendedsig module into the ++core grub image is recommended. ++ ++Certificates can be managed at boot time using the @pxref{trust_certificate}, ++@pxref{distrust_certificate} and @pxref{list_certificates} commands. ++Certificates can also be built in to the core image using the @code{--x509} ++parameter to @command{grub-install} or @command{grub-mkimage}. ++ ++A file can be explictly verified using the @pxref{verify_appended} command. ++ ++Only signatures made with the SHA-256 or SHA-512 hash algorithm are supported, ++and only RSA signatures are supported. ++ ++A file can be signed with the @command{sign-file} utility supplied with the ++Linux kernel source.

If a ++certificate is built into the grub core image with the @code{--x509} parameter, ++the variable will be automatically set to @code{enforce} when the appendedsig ++module is loaded. ++ ++Unlike GPG-style signatures, not all files loaded by GRUB are required to be ++signed.
